            <title>[SERVER-55314] Transaction may not apply correctly if namespace does not exist in tenant migrations</title>
                <link>https://jira.mongodb.org/browse/SERVER-55314</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;While creating the tenant migrations transactions passthrough, I noticed that if a transaction contained a &lt;tt&gt;createCollection&lt;/tt&gt; command and a few &lt;tt&gt;insert&lt;/tt&gt; commands onto that collection, some of the inserts would fail to be applied on-disk. This seems to be because we &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e16dbf0d24cbf1480469417098405f39daa0ebac/src/mongo/db/repl/tenant_oplog_applier.cpp#L867&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;allow the insert ops to be applied in different writer threads from the createCollection op&lt;/a&gt;. If the insert ops are applied first, they fail with a &lt;tt&gt;NamespaceNotFound&lt;/tt&gt; error. However, the migration doesn&apos;t fail because &lt;a href=&quot;https://github.com/mongodb/mongo/blob/138acafd27f145622506ef422a48c056fb4883df/src/mongo/db/repl/oplog_applier_utils.cpp#L322-L327&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;we catch &lt;tt&gt;NamespaceNotFound&lt;/tt&gt; errors and simply proceed with the applying the rest of the writer vector&lt;/a&gt;. The end result is that the insert ops simply aren&apos;t applied.&lt;/p&gt;

&lt;p&gt;One straightforward approach to resolve this would be to ensure that all applyOps operations in a transaction are serialized into the same writer vector.&lt;/p&gt;</description>
